So Naruto is finally on his 3rd step of training to master that move left by the 4th... even with Jiraiya's demonstration of it on that tree it doesn't look nearly as strong as Sasuke's and Kakashi's Chidori. Chidori was blowing up big chunks off the huge boulder and the 4th's move is just making a hole in that tree.

So I thought that Chidori might be really buff because of the whole high speed thrust, but in the Anime, right when Sasuke starts the Chidori, you notice that the walls are cracking and when he runs with it, the wall is getting torn apart just from the Chakra generated around his hand.

But the 4th's move is supposed to better isn't it? Jiraiya said it was the 2nd hardest level of move to do and took the 4th 3 years to master it.
